Powdery mildew at Harvest - HELP! URGENT!

So I thought I'd eradicated my mildew problem. I had noticed it a few weeks back and had treated it with several 4 hour long hits with a sulphur vaporizer. I cut them last night and as I got to the outskirts of the garden, (which gets neglected due to its difficulty in accessing it) - I noticed the plants were ravaged with it.
I don't have anywhere to hang them but all together so it was impossible to isolate the worst of it, though I hung the ones that were infected off to the side at least.
I'm scared to spray them as they're now in the dark, at 50 degrees and just begging for budrot.
A friend suggested putting the lights back in, only hanging them low, below the plants, to increase the temperature and speed up the drying process. I'm scared to do this, but I think I will, just to contend with the cold factor. Unless you've got better advice. I'm worried about space heaters left unattended., so that rules that out.
So, is there anything I can do to kill the mildew at this point without getting boryitis? Sulpur vapor would make the buds taste nasty wouldn't it? Could I hit them with the vapor and then air it out?

I think that might be your only option from the sounds of it...I might even take the moldy parts and put it in a paper bag away from the rest of it to dry..that way it's seperated and at least some of the bud wont be affected..

some have used this with good result. Not approved for edible foods except those darn apple trees. I've read some posts of people having success with it, sorry I don't have a link. Some express concern with smoking I'm trying to contain a mildew in l8 budding
myself and I have such a small grow I've used baking soda in water with a bit of dish soap. the Ph neutralizes the Mildew I guess it can not grow in a high alkaline environment like the baking soda will provide. Hope everything turns out better than ok.


Physan 20

Physan 20 is a fungicide, bactericide and algaecide which kills powdery mildew, rust, other fungi and even fire blight on contact. Physan 20 is a contact killer, not a preventative.
Physan 20 is extremely safe to use. It biodegrades within 50 hours, and leaves no residual in the soil or on your plants. It is near neutral so it will not affect your soil pH.
